R. A. GOELLER CONNECTOR Original Filed April 29, 1935 n 9 am, m. ATTORNEY l atented June 27, 1939 UNITED STATES PATENT OFFICE.

Divided and this application March 27, 19:1, set-a1 No. 13am 1 Claim. 40. its-26s) This invention relates to connecting means and particularly to devices for forming a flrm electrical connection between cables or other conductors.

In my co-pending application, Serial No. 668,- 487, now Patent No. 2,093,372, granted September 7, 1937, of which this is a division, I disclose a form of connector .of this character wherein a body member and a. yoke member are adapted m to be drawn into clamping engagement with the conductor by means of a tapered bolt or nut which engage tapered openings in the yoke and body member. In accordance with the"present invention, provision is made whereby one ofthe 15 members, such as the bodymember, is formed as a lug towhich a conductor may be bolted or riveted or attached in any appropriate manner.

Among the objects and advantages-of my invention are, to provide a device of this character which is' composed of few parts all of which are simple in construction and economical to manufacture and also to provide a device of this character which is strong and durable in use and -Which may be readily applied to and removed p 25 from a conductor.

Other objects of myinvention will appear from the following description taken in connection with the accompanying drawing, wherein; Figure 1 is a perspective view of a coiinector 3o embodying one form of my inventionf Figure 2 is a sectional View taken on the line 22 of Figured; and p Y Figure 3 is a top plan view of the connector.

Referring to the drawing, A represents a yoke 35 member adapted to embrace a'body or lug member B.- The body member 13, as shown h ng ure 1, is substantially L-shaped in cross section and comprises an upright portion ll adapted to be received between the sides ll of the yoke 40 member A and extended portion l2, formed with openings 13 for the reception of bolts or other means for attachment thereto of a conducting bar such as a busbar. lit-will be seen from the drawing that the lugporiaon I2 is wider than 45 the upright portion II and where the metal of the lug is narrowed to join the upright portion, it is thickened outside the yoke to provide the proper current carrying capacity. The body member. III is formedlwith a recess or jaw Ii alignment, and the body portion B is formed with V and a straight screw-threaded shank 29 adapted to be engaged by a tapered nut to. The'nut is slotted from its'inner end as shown at ii in Figure 2.

To apply the device to the conductor, the yoke is placed over the conductor, the portion it of the body member E inserted between the. sides of the yoke, the bolt 21 inserted through the side opening '20 and central opening 2| and the nut 30 is applied and tightened. The tapered faces of the nut and bolt head engage respectively one side of the openings 2| and the opposite side of the opening 20, as shown in Figure 2 and tightening oi the bolt draws the jaws. l5. and I8 tnward one another and clamp the con'ductorbevgo tween the jaw ii of the yoke and the opposite jaw II of the body member, the jaws clamping tightly i'nto the metal of the conductor.

- It willbe noted that in clamping the conductor, the clamping pressure is exerted against opposite sides of the nut and the stress produced by this pressure'is shearing rather than bending. It will also be noted from Figure 2, which shows the parts in clamped position, that the shank of the bolt is free in the. opening 2i and the shank is not subject toany bending stress. Due 'to the split form of the nut 30 and its angle of taper, the friction of the nut against the walls of the openings 20 and 2| is greater than the friction. of the nut on the screw threads of the bolt. The result of this is that the bolt may betightened or loosened by application of a wrench to the bolt head without the necessity of holding the nut or vice versa. V The slidable yokes will usually be made oi brass or some other hard alloy of copper, the .bolt and nut of steel or high strength non-ferrousmetal and the'body portion,-which forms a direct connection between the conductors, of copper or a I pp r oy.

5 The combination with a pair'of members slidright portion'having an inwardly tapering openpling of pipes or structural units, such as rods, of theextension outside "said yoke being narbars and thelike. v rowed and thickened as it joins the upright por- Having now described my invention, what I tion,'said yoke having aligned inwardly tapered claim and desire to secure by Letters Patent is: openings at opposite sides thereof and said upable with respect to one another, one of said 111g therethrough and screw wedge means ex-' members being formed as a yoke of flat metal tending throughsaid openings and adapted to and the other as'an L shaped body member commove the body and yoke member relative to one prising an upright portion of rectangular secanother to clamp a conductor between them.
